Multi-photon Up-conversion Luminescence of ErP ₅ O ₁₄ Noncrystalline

Abstract

In this paycr we report the observation of multi-photon up-conversion luininescence phenomenon of ErPS014 noncrystalline induced by pulse DCAI dye laser and clarifjg that ihe mechanism of up-conversion is the step t).v step ahsorption of single E?+ ion.

Three-photon phenomena in the upconversion luminescence of erbium–ytterbium-codoped phosphate glass

“…Studies of the upconversion luminescence in Er/Yb codoped phosphate glass will allow greater understanding of the energy transfer and transition mechanisms in these materials and may prove beneficial in the development of short wavelength ͑e.g., green͒ lasers. Chen et al 3 have studied the upconversion luminescence of erbium-doped phosphate glass excited by a dye laser. Lu et al 4,5 reported the upconversion luminescence of erbium-doped phosphate glass and fiber excited by Nd:YAG laser.…”

“…7,8 Usually only the two-photon upconversion processes are observed, and the mechanism of these two-photon transitions has been extensively analyzed in Er/Yb-codoped materials. [3][4][5]9 In this letter, we present the three-photon upconversion process in Er/Yb codoped phosphate glass. Our efforts have focused on measurement and characterization of the three-photon upconversion process in Er/Yb codoped phosphate glass.…”

Luminescence Properties of Dy3+-Doped CaLaP3O10 White-Light Phosphors Under Vacuum Ultraviolet Excitation

“…In recent years, luminescence materials doped with Dy 3+ have attracted broad attention due to its white emission under vacuum ultraviolet excitation [1][2][3][4] . As a rule, Dy 3+ has two prominent bands in the emission spectra in many host matrixes.…”

“…Rare-earth-ions-doped phosphate-based luminescence materials have been applied in various fields, such as colour televisions, mercury-free fluorescence lamp and visible light [1][2][3][4][5] . So it can be inferred that orthophosphates are potential host crystal for its application in vacuum ultraviolet range 6,7 .…”

The electronic structure and photoluminescence properties of Ca2GeO4:Eu3+ in ultraviolet and vacuum ultraviolet region

“…Many efforts have been made to discover host materials as well as activators with high performance [1][2][3]. Recently, germanates have attracted much attention and have been widely investigated as new host materials for light emitting devices (1) For application in FEDs, Xiao et al [4] and Minami et al [5] have reported the (Zn 2 SiO 4 )-(Zn 2 GeO 4 ):Mn 2 þ as an efficient phosphor.…”
